Crest Nicholson Plc intends to sign the building safety pledge set up in the aftermath of the Grenfell fire in 2017 to improve standards that may cost the U.K. developer as much as 120 million pounds ($157 million).

The company’s best estimate of further liability as a result of the pledge would be 80 million pounds to 120 million pounds, according to a statement Tuesday. Since 2019, Crest Nicholson has recorded 47.8 million pounds of net charges from obligations imposed after the fire at Grenfell Tower in London in which flammable cladding materials contributed to the deaths of 72 people.

The Secretary of State for the Department for Levelling Up, Housing and Communities announced in January the government’s intention to increase the legal obligation on developers to fix potentially dangerous buildings. Since then, Crest Nicholson has engaged in “intensive dialogue” with the government about the new guidelines, resulting in the decision to sign the pledge, the firm said in the statement.

The new restrictions will be enacted in law through proposed amendments to the Building Safety Bill that is currently passing through parliament. Crest Nicholson is currently considering whether any further regulatory approvals are required in respect of the proposed laws, according to the statement.
